FYI: for those interested in Fedora, I thought I would pass on an announcement from Paul Whalen recently sent to the fedora-arm mailing list...you can now pick a remix image using the links highlighted below...
Good afternoon folks,
David Marlin has posted a new Aarch64 Fedora Rawhide Remix for those interested in upgrading from the F19 bootstrap image.
The remix includes a lookaside repository[1] to provide a patched kernel and packages not yet built for aarch64.
Instructions for downloading and using the remix have been added to the Quickstart[2] page.
Paul
